Since the Acer A100 comes with meager 5.4 gigabytes of flash storage, you might want to store applications on the micro SD card but the ICS removes provision to store apps on sd card. So how do you do it?
First you need to be rooted and have micro SD card installed on your tablet.
– Download and unzip the attached file and put it in the root of your internal sdcard (/mnt/sdcard)
– Open root explorer and navigate to /mnt/sdcard (if its not already there) tap and hold on the file install_recovery.sh and pick the copy option
– Now navigate to the /etc folder tap the Mount r/w button
– Find the install_recovery.sh file tap and hold it, then select the option rename. Change the name to install_recovery.bak and then tap paste to copy over the new file.
Now look just under the file, you’ll see the date and permissions, it should say something like rwxrwxrwx if it does not you’ll need to tap and hold the file tap permissions and check all three boxes for read and execute.
Once you’ve done the above steps reboot and wait about a minute after your tab comes up, goto settings and look at your storage space to see if the internal space size has changed.
To reverse just delete the install_recovery.sh file, rename the backed up one and reboot. If you decide to keep this mod, you’ll want to copy the contents of /mnt/external_sd to /mnt/sdcard so you dont loose any of your app data. Also, you’ll no longer need GL 2 SD or any other mod to fetch data from your micro sdcard.
